\section{SNMP Walk}
The SNMP Walk feature comes in handy if you connect a new switch and don't know
which OIDs can be requested or if you just want to know how many oids in the
interface description for instance are available.
At $(1)$ you can enter the start oid. The SNMP walker tries to get all the
children of the given start oid, so if you want to perfom a full walk, just
leave it empty or put a one in it. In case you only want to get for example all
the subnodes of the system oid, just enter its oid sequence and only the children
will be requested. 
At $(2)$ you can select the switch and at $(3)$ you got the possibilities to
start the SNMP walk, to stop it, to save the results to a file and to close the
SNMP walk.
